Tidy JSON - JSON Pretty Printer/Colorer

Tidy JSON is a console-based syntax highlighter
and pretty printer for JSON text (RFC 4627).
Below is a screenshot of Tidy JSON in action:

Tidy JSON can format JSON
text stored in a file or supplied over
standard input. To format JSON text in a file, simply specify
the path to the file as the program argument. If no file path
is specified then Tidy JSON expects JSON text to arrive over
standard input. Use the --help argument for full
usage and help.

Tip:
To format JSON text downloaded as part of an HTTP transaction,
use wget
and pipe the output to tidyjson. To format JSON text
from any application or in web pages, copy the selection to the
clipboard, paste it to the standard output using
Clipboard Tool and
then pipe to tidyjson.
